Here's a really good article on this here - https://www.nature.com/articles/d41586-021-00450-z
The best way to answer your questions is to do a challenge test where some hardy souls/heroes/people desperate for cash/complete mugs get deliberately infected with SARS-COV2. A trial is about to be started here in the UK - https://www.gov.uk/government/news/w...oval-in-the-uk |
Is there any vaccine in existance that actually stops anyone being infected? Surely all a vaccine does is prepare the immune system to recognise and fight an infection quicker than the immune system starting from scratch.
